So.....when did erika learn dark magic am i missing something

They definitely know how to make one unit look more interesting than the other ones. Honestly, they made Myrrh such a desired unit by making her a flier AND have Hone Dragons, the other two look like crap in comparison to her in terms of hype.

I'll pull for green on my free summon, but that's about it. More excited for Lyon and Marisa than any of the units on the banner.

The most popular sword unit, Marisa, is coming via TT reward, but I agree a different red would have been nice.

It is Eirika's connection to Lyon and this seems more like an alternate universe Eirika as she does not know magic in game.

I’ve been saying the same thing. Why do this? Just put Ross or Cormag or some other mainstay. Even Duessel would have been fine by me! But not some fucked up variation of Eirika. I’m legitimately pissed that they did that instead of putting a realistic game unit in place.

it's just that...
Spoiler

Eirika gave Lyon the sacred relics, so it could be alternate universe where she's tempted by the dark side and be a dark mage *lol*
Or her mercenary alt, Erina whom she introduced herself to Selena.

I don't even know. Saleh is a Sage, and they have a support and ending together. I blame him.
